That time my father in law told me my shed foundation was all wrong
Back when I built my first shed about 15 years ago, I put it on cinder blocks on top of packed gravel. Thought I did it right. Then my father in law came by, kicked one of the blocks, and said those blocks will shift after two good freezes. He was right. After that first winter, the whole floor had a noticeable tilt. I ended up tearing it down and pouring a proper concrete slab with rebar. Cost me about $400 more than the original plan, but that shed is still level today. Has anyone else learned a hard lesson about foundations the expensive way?
